Constructive arrangement applied to a mattress

ABSTRACT

A mattress having of a center and a perimeter edge, including threads endowed with longitudinal cavities which, when glued or welded to each other, form a mattress capable of reducing costs and bringing significant improvements to the technological sector of mattresses, as well as making the mattress recyclable to form a new mattress, whose field of application pertains to the technological sector of mattresses.

INTRODUCTION

The present patent application refers to an unprecedented constructivearrangement applied to mattresses, and is designed to reduce costs andbring significant improvements to the technological sector of mattresseswhich, moreover, at the end of its useful life may be used to form a newperimeter edge by means of recycling.

FIELD OF APPLICATION

The innovation now claimed is applied to the technological sector ofmattresses.

Technical Problem to be Solved

One of the oldest inventions of the world—the mattress—is currentlymanufactured with perimeter edges and center made of polyurethane foam,or cluster which is comprised of leftovers of polyurethane foams pressedand heated to shape the format and resistance necessary so that saidperimeter edge receives the strength applied by the weight of the user.

However, the perimeter edges and the center of the conventional mattressare made of polyurethane and are not recyclable, which generates anenvironmental problem regarding the handling of the disposal of themattresses.

Another technical drawback of polyurethane foam used in making theperimeter edge and the center of the mattress is that it comprises opencells, which leaves the mattress prone to the proliferation of fungi andbacteria. Nevertheless, being comprised of open cells to acquireresistance and compression, the conventional perimeter edges have theirdensity increased, which leads to the increase in final weight of themattress.

STATE OF THE ART

The current state of the art anticipates certain patent documents whichrefer to the subject matter in question, such as document BR102015003989-1 A2, entitled “Spring mattress and process formanufacturing same”, which shows a mattress characterized by two sides(3) and (4), cut or manufactured from expanded polystyrene (EPS).

The above document discloses two sides that make up the edge of themattress, both comprising a solid format. Therefore, it disclosesdifferent sides to the application now claimed, which proposes an edgeendowed with hollow longitudinal cavities.

Document BR 102016003200-8 A2, entitled “ARRANGEMENT APPLIED TODOUBLE-FACE MATTRESS, PROCESS FOR MANUFACTURING MATTRESS”, is comprisedof ends made of polyurethane Polyframe (2).

The above document discloses two sides that make up the edge of themattress, both comprising a solid format made of Polyframe foam, whichdiffers from the sides of the application now claimed which, as alreadymentioned above, is designed to shape a perimeter edge endowed withhollow longitudinal cavities for greater resistance to compression, aswell as a reduction in weight of the perimeter edge.

OBJECTIVES OF THE INNOVATION

It is an objective of the present innovation to propose a mattress thatcomprises a perimeter edge and its entire center made of polyethylenewith closed cellular structure, which contributes with waterimpenetrability or a water vapor imperviousness; further, it is designedto decrease the possibility of propagating fungi and bacteria in themattress;

It is an objective of the present innovation to propose a mattress witha perimeter edge and its center made of polyethylene having lowerdensity and greater resistance to compression, compared to polyurethanefoams;

Lastly, it is an objective of the present innovation to propose amattress with a perimeter edge and center made of polyethylene, which atthe end of its useful life is recycled for the production a newmattress, upon undergoing recycling.

SUMMARY OF THE INNOVATION

A CONSTRUCTIVE ARRANGEMENT APPLIED TO A MATTRESS presents a structurecomposed of threads endowed with longitudinal cavities, which are joinedby way of plastic weld with a thermal blower, forming a perimeter edgefor a mattress.

The innovation is made of polyethylene comprised of pores or closedcells which contributes with water impenetrability or water vaporimperviousness, as well as decreased possibility of propagating fungiand bacteria in the mattress. However, it may undergo modifications inits resistance and weight, and also be used to shape a new perimeteredge for a mattress at the end of its useful life, by recycling.

Advantages of the Innovation

In short, the main advantages of the perimeter edge are:

-   -   Reduction of weight in the mattresses;    -   Reduction of fungi and bacteria in the mattress;    -   Recycling;    -   Flexibility;    -   Resistance to compression;    -   Water impenetrability or water vapor imperviousness.

DETAILED TECHNICAL DESCRIPTION OF THE INNOVATION

The CONSTRUCTIVE ARRANGEMENT APPLIED TO A MATTRESS refers to a mattress(1) endowed with a center (2) with a perimeter edge (3), composed ofthreads (4) endowed with longitudinal cavities (5) which, when welded orglued to each other, form a center (2) and a perimeter edge (3), capableof reducing costs and bringing significant improvements to thetechnological sector of mattresses, and also of making the center (2)and the perimeter edge (3) recyclable to form a new mattress (1).

More particularly, the mattress (1) is composed of a structure (E),which is arranged by the center (2) and the perimeter edge (3),comprising threads (4) endowed with longitudinal cavities (5), and thethreads (4) are joined by way of glue or plastic weld (X) with theassistance of a thermal blower, forming an innovated mattress (1).

It is worth pointing out that the mattress (1) is composed of a center(2) and a perimeter edge (3) made of polyethylene, comprising pores orclosed cells (S) which contribute with water impenetrability or watervapor imperviousness, and also decreases the possibility of propagatingfungi and bacteria in the mattress (1). Nevertheless, it may undergomodifications to improve its resistance to compression and weight, andto be used to shape a new mattress (1) at the end of its useful life, byrecycling.
